Objective To investigate the epidemiological characteristics of Brucella aggregation of disease outbreaks, and explore the causes and possible routes of transmission in Tongxiang City for proposing prevention and control measures.Methods A case investigation was done to the first case of bovine brucellosis, while search of new case was carried out in the population.Epidemiological survey was carried out in accordance with the case study form from Chinese Center for Disease Control and Prevention that developed the unified form, at the same time, survey of risk factors were carried out.According to the principle of informed consent, blood samples were collected, brucellosis rose bengal plate agglutination test (RBPT) and tube agglutination test (SAT) were used, and positive specimens were identified by Brucella culture.Brucellosis diagnosis was based on Brucellosis Diagnostic Criteria (WS 269-2007).Results The first case was a male Fifty-six years old wine salesman from the farmers market.Serum of the patient was (+) in RBPT test, and 1 : 400 (++) in SAT test.Cattle Brucella was check out by blood culture.Totally 66 human serum samples from the case search in key groups were tested, three people were detected seropositive but Brucella culture result was negative.Three cases were determined latent infection who had contacted beef sales staff.Conclusions The survey has shown that it is possible to get infected through contact with respiratory, skin, mucous membranes of Brucella infected beef or contaminated environment.Epidemic form should be concerned of non-professional personnel who are infected with different isoforms of brucellosis.The training of clinicians should be strengthened to improve their diagnosis and treatment technology.Health education should also be carried out to raise awareness of key population of disease prevention.

Objective: : To observe whether cytokines rIL 2,TNF ?,I FN ? and anti CD3/anti glioma bispecific antibody(BsAb) can work coordinately, and to investigate how to further enhance cytotoxicity of T lymphocyte against human glioma cells by BsAb. Methods: There were 12 groups,contr ast method were used to analyze the effect of cytokines rIL 2,TNF ?,IFN ? to cytoxicity directed by BsAb by single and combined experiments. Cytotoxicity was assayed by standard 18 h 3H TdR incorporation release. Resul ts: rIL 2,TNF ?,IFN ? and BsAb could cooperatively enhance the cy totoxicity of effect cells( P

Objective: To study bidirectional binding ability and immunoactivity of anti-CD3/anti-glioma bispecific antibodies(BsAb) , and to study its effect on T lymphocytes cells. Methods: Elution from standardized gel column and immnuohistochemical method were used to testify the relative molecular mass of the compound. ELISA method was used to detect its bidirectional immunoactivity and potential T lymphocytes' cytotoxicity. Phenotype and shape of T lymphocytes were also observed. Results: The relative molecular mass of the compound was 110 000, and it combined with both T lymphocytes and glioma cells.Immunoactivity assay showed the compound had good bidirectional immunoactivity. It also enhanced T lympocytes anti-tumor activity. Immunoactivity of BsAb combining with T lymphocytes was 1∶32 000, and combining with glioma cells was 1∶8 000;In phenotypes, CD3 + cells were the major one when cultivated with BsAb/IL-2, CD8 + cells increased gradually with cultivation time. Conclusion: These compounds are bispecific antibodies with bidirectional combining activity to T lymphocytes and glioma cells, they also have bidirectional immunoactivity and can activate T lymphocytes

ObjectiveTo investigate the regulatory effects of Ginkgolide B on the biological characteristics of brain T cells and their interactions with glial cells during the recovery phase of ischemic stroke in mice. Methods36 adult C57BL/6 mice were randomly assigned to three groups: sham-operated group (Sham group), control group (PBS group), and Ginkgolide B treatment group (GB group). The Sham group underwent only sham surgeries, whereas the PBS and GB groups were subjected to a middle cerebral artery occlusion (MCAO) model using the filament method, followed by intranasal administration of an equivalent volume of either PBS or Ginkgolide B solution for 14 days post-injury. Neurological function changes were evaluated in all three groups using the rotarod test and a neurological scoring system. On day 15, single-cell sequencing was performed on fresh tissues from the brain injury areas, surrounding cortex, corpus callosum, and striatum of mice in the PBS and GB group to assess the biological characteristics of T cells and their subpopulations, and further explore the interactions and mechanisms among T cells, microglia, and oligodendrocytes. ResultsCompared with the Sham group, both PBS and GB group exhibited significant improvements in neurological scores and reduced pre-fall motor durations (P < 0.001). Compared with the PBS group, the GB group showed a downward trend in neurological scores and an upward trend in pre-fall motor durations on days 5, 10, and 15 post-ischemic brain injury, with a significant increase in pre-fall motor duration on day 15 (P < 0.05). Compared with the PBS group, the GB group exhibited a significant increase in T cell proliferative activity in the brain 15 days post brain injury (P < 0.05). The number of proliferative T cells and the levels of lipid metabolism were significantly elevated (P < 0.05), and there was a significant increase in extracellular matrix remodeling in all T cells (P < 0.05). Additionally, the interactions between T cells and both microglia and oligodendrocytes, as well as among the microglia themselves and between microglia and oligodendrocytes, were significantly enhanced in the GB group. This was primarily evident in the strengthened interactions between CD74 and macrophage migration inhibitory factor (MIF), as well as colony stimulating factor 1 receptor (CSF1R) and colony stimulating factor 1 (CSF1) (P < 0.05). However, the inflammatory levels of T cells showed no significant differences compared with the PBS group. ConclusionA mouse model of ischemic stroke can be successfully established by MCAO operation. Ginkgolide B may promote neurological recovery post-brain injury in mice by modulating the biological characteristics of T cells within the brain and their interactions with glial cells.

Objective:To analyze the efficacy of neuronavigation‐guided pure endoscopic endonasal transsphenoidal approach for the surgical removal of complex pituitary adenomas .Methods :The clinical data of 60 patients who received pure endoscopic endonasal transsphenoidal surgery for complex pituitary adenomas from Apr 2010 to Sep 2012 was retrospectively analyzed .

Objective To explore the effects of information-motivation-behavioral (IMB) skills model based WeChat education on the treatment compliance, the self-efficacy and the quality of life of diabetic nephropathy patients.Methods A total of 92 patients with diabetic nephropathy treated in Danyang People's Hospital from January 2015 to June 2016 were selected as the research object by convenient sampling method and randomly divided into observation group and control group according to the random number table, with 46 cases in each. The control group received conventional WeChat health education, and the observation group implemented WeChat health education based on IMB model. The treatment compliance, the self-efficacy and the quality of life were compared between the two groups 6 months after the nursing intervention. Results There was no statistically significant difference between the two groups of all dimensions and the total scores of treatment compliance before intervention (P>0.05). All the dimensions of treatment compliance of the observation group were higher than those of the control group after intervention, and the differences were statistically significant (t=3.365, 3.258, 3.989, 2.655, 3.513, 4.674, 3.747, 4.187,3.578;P<0.01). The change degree of the 10 dimensions of self-efficacy and total scores were all greater than those of control group, the differences were statistically significant (t=4.854, 5.632, 4.854, 4.241,3.896, 3.785, 3.789, 3.325, 3.314, 3.817,4.123;P<0.01). The improvement of all the dimensions of patients' life quality and its total score were all higher than the control group after intervention, with significant statistical difference (t=5.965, 4.763, 4.746, 4.547, 3.869;P<0.01).Conclusions Application of IMB model based WeChat health education on diabetic nephropathy patients can significantly improve the patient's treatment compliance, self-efficacy and quality of life.
